In addition, in the lighting fixture using this LED lamp, there is a type in which the ballast of the existing lighting fixture is used as it is, and the existing lighting fixture is modified and the ballast of the lighting fixture is removed, and the LED lamp is directly attached There is a type that supplies AC power. The LED lamp is supplied with power from the caps at both ends of the lamp, and the LED element is turned on by supplying power to the LED element with the received power supply. Therefore, the LED lamp is used for the purpose of securing brightness with power saving as an alternative to the existing fluorescent lamp.
